I keep seeing people say this without explaining what the huge thing strapped to the actor's face is, that clearly isn't a phone. Not explained in the article either.
I’m not sure what you mean. There’s one shot in the video where they show a full motion rig and clearly explain that this system works with both a phone and/or a professional stereo system.
I’m guessing that is for when you want to move your body around and capture the facial expressions associated with doing so. You need some sort of rig to keep the camera in your face if you’re moving your face.
